Listen up, 3D fanatics - according to TmoNews, LG's multidimensional G-Slate will go on sale on April 20th.

It's not the first time we've seen this date thrown around, and it would certainly make sense given the fact that two of T-Mobile's other flagships - the G2x and the Sidekick 4G - are also launching on 4/20.

2 of T-Mobile's most exciting devices that are arriving this month, the dual-core LG G2x and the Samsung Sidekick 4G, have just gone live on Wirefly's pre-order site. Wirefly, one of the largest online mobile retailers, is sweetening the deal on the G2x by $50 compared to MSRP and on the Sidekick 4G (pick black or pink) by $20.

Both devices come with free activation for the pre-order period and, of course, ship for free as well.

Thanks to Radio Shack, it's no surprise that the Sidekick 4G is hitting the sales floor on April 20th for $99, but T-Mobile has finally made an official announcement via its Twitter page. In the interest of consolidation, it was also announced that the LG G2x would be available in-store for $199 after a $50 mail in rebate, but If you just can't wait to get your hands it, you'll be able to grab it online starting April 15th.

While T-Mobile still remains quiet about the Sidekick 4G's release date, it looks like RadioShack just couldn't keep the news any longer. Thanks to a tweet from the official RadioShack Twitter account, we now know that the Sidekick 4G will be available on April 20th. That's pretty exciting news for those looking to grab the newest version of the ever-so-popular texting machine, especially when combined with the $99 (with a two year contract) price tag.

The new G2x dual-core phone with stock Google experience is not the only device getting some attention today in a slew of T-Mobile press releases - both the G-Slate 3D tablet made by LG and the Sidekick 4G made by Samsung finally got pricing information.

First up, the 8.9" G-Slate tablet running Android 3.0 "Honeycomb" will cost $529.99 after a $100 mail-in rebate (ugh). Don't get too excited though - this price is for a 2-year contract, in addition to a voice line (hmm?

The reincarnation of the Sidekick brand didn't quite come as a complete surprise after T-Mobile teased its return back in January, followed by a nice photo leak that showed the latest thumb-killer, this time made by Samsung, in its full glory. However, it's always nice to get official confirmations and specs from the carrier itself, and that's exactly what T-Mobile is gracing us with today.
